Abstract: Method for the recovery and repair of eyesight through which out of the two eyes the weaker eye in need of repair or recovery is determined; both eyes are assigned an optical element influencing the passage of the incident light; the path of the light reaching the eye is periodically interrupted, thereby forcing the eye to perform additional focusing activity, so that transparency characteristics of the optical element assigned to the chosen or designated eye are left unchanged, and the transparency characteristics of the optical element assigned to the other eye are modulated so that the passage of incident light into the other eye is blocked and then unblocked with a frequency in the 0.2 Hz to 0.8 Hz range.
